USG v1.0 Hardware Firewall

The USG is the original open-source firewall for your USB ports. It connects between your computer and your USB device, isolating malicious firmware and keeping your computer safe.

Operating at USB 1 speeds (12Mbps), the USG is great for protecting your low speed devices like keyboards and mice. The open-source firmware is ideal for security researchers and developers. For quick access to flash drives and hard drives at USB 2.0 speed, consider the Armadillo.
